CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Provisional Patent Application No. 63/352,069, filed Jun. 14, 2022. The entire content of this application is hereby incorporated by reference for all purposes.

BACKGROUND 1. Field

The present disclosure relates generally to user interfaces of computer systems and, more specifically, to performant configuration user interfaces used to configure products for build-to-order workflows and session collaboration between a plurality of performant configuration user interfaces.

2. Description of the Related Art

Many types of products are built-to-order, with the product design being specified by the buyer in advance. Often, buyers configure the product within some design space constrained by a menu of options. For example, homebuilders may offer a preset menu of options for countertops, flooring, cabinets, and fixtures, and before having a house built, a homebuyer may choose among these options to specify their design. Similar workflows are applied in other build-to-order offerings, like furniture, computers, clothing, landscaping, automobiles, and the like.

Often, the design space is relatively high dimensional and granular, which can make it difficult for users to effectively navigate among their options to arrive at a design they will ultimately prefer to other available designs. A design space for a house, for example, may have more than 10,000 or 100,000 different configurations that are possible with every permutation of surface material, fixture, layout, and the like that can be combined. Users generally do not want to, for example, view 10,000 images of a room to decide which they like best.

SUMMARY

The following is a non-exhaustive listing of some aspects of the present techniques. These and other aspects are described in the following disclosure.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

To mitigate the problems described herein, the inventors had to both invent solutions and, in some cases just as importantly, recognize problems overlooked (or not yet foreseen) by others in the fields of image processing and human-computer interaction. Indeed, the inventors wish to emphasize the difficulty of recognizing those problems that are nascent and will become much more apparent in the future should trends in industry continue as the inventors expect. Further, because multiple problems are addressed, it should be understood that some embodiments are problem-specific, and not all embodiments address every problem with traditional systems described herein or provide every benefit described herein. That said, improvements that solve various permutations of these problems are described below.

Some embodiments improve upon existing computer implemented tools to help users choose among their options and in build-to-order workflow. Some embodiments implement a set of user interfaces that help users to quickly navigate a large, relatively high dimensional design space (e.g., as complicated or more complicated than those mentioned above) by improving the speed of the user's navigation through various windows and views. Some embodiments include two stages of user interfaces, with a first stage in which the user can dynamically adjust compositing of a stack of images to select various candidate designs, and a second stage in which the user can dynamically adjust which portions of a field-of-view depict one design or another, for instance by sliding a user interface element left and right or up and down, to dynamically adjust how much of the field-of-view depicts one design or the other on either side of a corresponding line adjusted with the sliding action.

Some embodiments may further substantially reduce memory computational complexity of design sessions with a data structure for images that scales favorably with the design space, e.g., a number of images needed to support operations may scale at a substantially lower rate than the number of supported designs in a design space. Some embodiments may implement compositing (e.g., alpha compositing) with techniques that reduce image artifacts near the edge of nontransparent portions of images in a stack. Some embodiments may reuse layers isolating given design options of given design elements across a relatively large number of designs involving those design elements and, in some cases, freeze a stack of layered images in a single flat image for use in the second stage user interface to afford relatively performant transitions. It should be emphasized, though, that embodiments are not limited to implementations affording all of these benefits, as various inventive aspects described can be used independently.

Some embodiments may further allow users to participate in a collaborative design session. Users can interact with each other via video, audio, or chat. Users may be able to establish a design session and obtain a first design configuration specified via a user interface. Each user may control the user interface independently of the other users but experience real-time updates to the design space within the user interface when other users make a design change.

FIG. 1 illustrates an example of a computing environment 10 in which the present techniques may be implemented. In some embodiments, the computing environment 10 is a distributed computing environment implementing a client/server architecture, though other architectures are contemplated, including monolithic architectures executing on a single computing device. In some embodiments, the computing environment 10 includes a server 12, client computing devices 14, a configuration engine 16, a rendering engine 18, and a network 20, such as the Internet, by which these components may communicate.

In some embodiments, the client computing devices 14 are desktop computers, laptop computers, in-store kiosks, tablet computers, mobile phones, head-mounted displays, or the like, executing an operating system and a web browser or native application in which the described user interfaces are presented. Three client computing devices 14 are shown, but embodiments may support substantially more concurrent sessions, e.g., more than 100, or more than 1,000 geographically distributed sessions around the US or the world.

In some embodiments, the server 12 is a nonblocking web server or application program interface server configured to service multiple concurrent sessions with different client computing devices 14, for instance implementing a model-view-controller architecture or other design. In some embodiments, the server 12 may dynamically generate assets, markup language instructions, and scripting language instructions responsive to requests from client computing devices 14 to send user interfaces to, or update user interfaces on, those client computing devices 14. The user interface may evolve over time (e.g., in a web application), in some cases, displaying new resources (e.g., images and other data) sent from the server 12 responsive to user inputs to the user interface.

The configuration engine 16 and rendering engine 18 may be used to generate image files and metadata used by the server 12 to generate the user interfaces, for example supplying resources depicting and describing options in a design space.

In some embodiments, the server 12 may execute a process illustrated in FIG. 2 , for example, by executing program code stored on a tangible, non-transitory, machine-readable medium. The illustrated operations may be executed in a different order, omitted, replicated, executed concurrently, executed serially, have additional operations inserted, all be automated, involve human intervention, or otherwise be modified relative to the arrangement depicted, which is not to suggest that any other description herein is limiting.

In some embodiments, the process 40 is preceded by one or more product manufacturers, which may be different tenants having different tenant accounts supported by the server 12, supplying a set of records characterizing a respective design space, among a plurality of design spaces. In some embodiments, the set of records may include computer aided design files specifying a spatial arrangement of a product to be manufactured, like a home, landscaping design, automobile, computer, furniture, or article of clothing. The set of records may further include various options for components, which may include different, substitutable computer-aided design (CAD) files for different shapes of components, like different fixtures, as well as different textures corresponding to different surfaces, like image files to be tiled over polygons that define a surface specified by the CAD files. In some embodiments, the records may further indicate which optional resources correspond to which surfaces or spatial areas of the CAD file. Options may further include lighting options, which may include attributes of the light to be used in renders.

In some embodiments, this set of records may be received by the above-described configuration engine 16, which may cooperate with the rendering engine 18 to provide data that allows the server 12 to obtain a set of images compositable to depict different designs in a design space, as indicated by block 42 in FIG. 2 . In some embodiments, the set of images may include substantially fewer images than there are possible designs supported in the design space. For example, the number of images may scale at a rate of less than some coefficient of the number of designs supported by a specified design space corresponding to the set of images, or the design space may have a number of designs that scales at an exponential rate relative to the number of injured images needed to depict all of the designs in that space or a lower rate. As a result, some embodiments may substantially reduce the computational complexity of the described operations in terms of memory complexity relative to more naïve approaches that obtain a different image for every single possible design in a design space. That said, embodiments are also consistent with this more naïve approach in some cases, for example, where the design spaces relatively low dimensional and coarse-grained.

In some embodiments, the set of images may include images like those described below in a technical description of an example embodiment having in-line images. In some embodiments, the set of images may include a base image depicting a field-of-view of the article of manufacture, or portion thereof, like a view into a kitchen of a house or commercial property to be designed, or into an automobile interior, or of a model wearing article of clothing. In some embodiments, the base image may have no transparency in the entire image or a portion depicting the field-of-view. In some embodiments, the base image is a three-dimensional perspective view of the field-of-view. In some cases, the rendering engine 18 may execute a ray-tracing algorithm to render the images, in some cases, masking or isolating given objects to create the templates described below.

In some embodiments, the set of images include template images to be overlaid on the base image to depict different design options. For example, the base image may depict a countertop with a blue surface, and a template image may include a view of that countertop with a green surface, both having the pixels depicting the countertop in the same positions in pixel space (e.g., at the same Cartesian coordinates in the image). In some embodiments, the template images may include a first portion with pixel values that are nontransparent and overlay and occlude pixels in the base image to depict the design option. The template images may further include a second portion with pixels that are transparent, such that when overlaid on the base image, the pixels of the base image are still viewable. The transparent pixels need not be perfectly transparent to qualify as such, provided the visual effect of the base image or other layered images remains for the viewer. For example, the transparent pixels may be less than more than 80% transparent, 90% transparent, 95% transparent, 99% transparent, or 99.9% transparent while still qualifying as “transparent.”

In some embodiments, the images in the set may be in a format that supports transparency, for example portable network graphics (PNG) format, joint photographic experts group extended range (JPEG XR) format, WebP format, or the like. In some embodiments, the image file format may include an alpha channel, separate from, for example, red, blue, and green channels that specify intensities for each of several colors constituting the pixel. In some embodiments, the alpha channel may specify transparency of the corresponding pixel at the coordinates of that pixel, like Cartesian coordinates of height and width. In some embodiments, the alpha channel may have a bit depth of 4, 8, 16, or 32 bits, or more or less corresponding to different degrees of transparency. In some embodiments, the image format may be a lossy compression format or a lossless compression format, depending upon design trade-offs in image quality, latency, and bandwidth consumption. Some embodiments may compress the image by segmenting it into square blocks, computing a discrete wavelet transform (e.g, with a fast Fourier transform) of various spatial variation of pixel intensity in the channel within each block, quantizing the resulting matrix by multiplying it with a quantization matrix tuned to down-res higher frequency components, and then compressing the result with run-length coding or dictionary coding. The client computing device may reverse this process with a suitable image decoder to determine pixel intensities and display the image, thereby conserving memory, bandwidth, and latency.

In some embodiments, each of the images in the set may have the same height and width in pixel space, such that when the images are overlaid, the position of the second portion in the template images is at a specified portion of the first portion, for instance causing an overlay of a countertop surface design choice to be in the proper position. Or in some cases, template images may be smaller and may include a height and width offset that specifies an alignment point for overlay.

In some embodiments, the template images are associated with a depth value, like an integer depth value, such as a z value, and template images may be applied to a base image in a stack according to these depth values, monotonically increasing or decreasing, depending upon the numbering scheme. This is expected to accommodate scenes in which portions affected by different design options overlie one another in the field-of-view.

In some embodiments, the images in the set may be created by the rendering engine 18 in cooperation with the configuration engine 16. In some embodiments, the configuration engine 16 may execute a script that causes the configuration engine 16 to generate polygon volumetric meshes and surface tiling of every permutation of supported design and provide those outputs to the rendering engine 18 to cause the rendering engine 18 to render corresponding images. In some embodiments, the rendering engine 18 (e.g., Unreal Engine from Epic Games Inc. of Cary, North Carolina) may be directed to generate a single base image for each three-dimensional polygon mesh and then generate template images for all options of textures that are supported in the design space. In some embodiments, this process may be repeated for multiple sets corresponding to different views of different portions of the product, and the operations described may be replicated for those different views. For example, a user may configure their kitchen in one set of user interfaces and their bathroom in another. In some embodiments, the images may be generated in advance of a session with the user with preprocessing, as image generation may be relatively computationally complex and time-consuming, possibly taking more than 10 minutes or 10 hours to cover all permutations of a design space. Or some embodiments may implement real-time server-side or client-side rendering, e.g., when the design space is particularly high dimensional and complex. The resulting images may be indexed according to the design options to which they correspond, and the configuration engine 16 may provide an ontology of those options along with the corresponding images to the server 12, which may store them in a repository for use when generating user interfaces in subsequent steps.

In some embodiments, the rendering engine 18 may be operative to perform certain operations to reduce edge artifacts in template images to improve the visual quality of composite images in which those templates are stacked on a base image, in some cases with multiple (3, 5, or more) such template images stacked. In some embodiments, the rendering engine 18 may implement alpha compositing with those template images. In some embodiments, the rendering engine 18 or associated raster graphics editor, may apply a Gaussian blur on the alpha channel of the template images (e.g., only the alpha channel and not in the other channels), for example a five pixel by five pixel Gaussian kernel, a three pixel by three pixel Gaussian kernel, or different size Gaussian kernel for a convolution may be applied to the alpha channel but not other channels, in some cases. In some embodiments, the transformation may be performed after converting the initial images from a non-linear color space, like sRGB, to a linear color space, and then after the transformation to smooth edges in the alpha channel, the images may be converted back to a non-linear color space. In some embodiments, the alpha channel may be a straight unassociated alpha channel or a pre-multiplied associate alpha channel. In some embodiments, these operations may result in a gradient of transparency at edges of the first portions of the template images, which are expected to reduce artifacts at edges, like ugly jagged lines and discordant color transitions in composite images displayed in client-side user interfaces. In some embodiments, the rendering engine 18 may include or may communicate with a raster graphics editor program, such as one scripted to implement these transformations or instructed implement these transformations through system calls, like Gimp or ImageMagick. Or some embodiments may implement compositing without adjusting the alpha channel, which is not to suggest that any other description is limiting.

In some embodiments, the process 40 further includes providing a first user interface by which members of the set are overlaid responsive to user inputs to depict different design configurations, as indicated by block 44. In some embodiments, this operation may be performed by the server 12 by sending markup styling and scripting what language instructions to the client device 14 responsive to a request for such a user interface (e.g., one including a user identifier by which the session may be associated with a profile), along with corresponding visual assets and data used to effectuate different views to be presented responsive to user inputs. In some embodiments, this transmission may be responsive to a request for a specific view or product from the one of the client devices 14, for example, via a web browser or native application. In some embodiments, the user interface may be provided by sending assets and data to a native application otherwise having code and other instructions needed to populate the user interface.

In some embodiments, providing the user interface may include sending images that are not immediately displayed to hold in a client-side cache to afford a relatively responsive updates to the user interface after user inputs. For example, some embodiments may send a subset of template images selected based upon a user's profile that are predicted to be likely to be chosen or were previously designated as “favorites.” In some embodiments, the user interface may take the form of that shown below in the appended technical documentation. In some embodiments, this first user interface may include inputs by which a user selects which design element is to be configured and inputs by which the user selects among options for that design element, for instance, by clicking, touching, or voicing spoken instructions to make selections. In some embodiments, user interfaces may be presented in virtual reality or augmented reality with a head-mounted display, and inputs may be implemented with gaze tracking or pointing. User inputs may be mapped to event handlers that update the user interface by manipulating a document object model to reflect the user's selection and update program state, e.g., swapping in and out template images in a stack of such images overlaying a base image to reflect user design choices.

In some embodiments, the first user interface executing on the client device may present these options and receive inputs from the user to select among them. Responsive to receiving a user selection of a given design option, the first user interface may access from cache or request from the server 12 a corresponding template image depicting the user selection (e.g., a given design option). The user interface may, upon receiving that image or accessing that image, determine a position in a stack of images currently composited in the user interface to receive the newly selected template image, based upon a depth value of the image and depth values of the other images in the stack, maintaining the stacked images in depth order in a composite view. In some embodiments, the images may be stacked in a div box in a document object model with which the user interface is implemented in a web browser. In some embodiments, the images that are stacked may have their position attributes set to absolute to control alignment as, for example, the screen is resized.

In some embodiments, the user interface may maintain a design state record for the session, which in some cases may be saved to a user profile server-side or client-side, so that the current state of the user interface may be re-created by, for example, replaying a set of user selections in a log, or stacking the specified template images for a design recorded in the profile. In some embodiments, the user interfaces may include an input by which a user may save their design or name their design.

In some embodiments, upon naming or otherwise designating a design, the stacked set of images may be flattened into a flat, single image of the design, which may be stored in memory in association with the user's profile (e.g., in client-side cache or server-side). In some embodiments, a design image may be named according to the response of a hash function to a text specification of the existing design, such that identical designs are assigned the same hash value as a name, and duplicate instances of the same design selected by different consumers may be maintained in memory with a single image file server side to save memory. In some embodiments, the flattening of the image may be performed server-side with the above-described image raster graphics editors, or some embodiments may flatten the image client-side, for example, by invoking WebGL functionality to expedite image processing operations via the browser by concurrently combining pixel values in a stack in different regions with different pixel shaders of a graphics processing unit (GPU) of the client 14.

In some embodiments, as a result of the user designating a design, some embodiments of the server 12 may obtain a first design configuration specified via the first user interface, as indicated by block 46. The specification may include identifiers of the images stacked in the design, a log of user edits to the design from the base design, or an inventory of design elements chosen in the design, for example. In some embodiments, this design configuration may be stored along with a plurality of other design configurations chosen by the user. In some embodiments, the server 12 may further store in memory a set of public design configurations (also referred to as designs), for example, chosen by interior design specialists or architects or other experts in the design domain, and users may also access these to compare against their own configurations or to compare configurations of designs from different preset alternatives.

Some embodiments may then provide a second user interface depicting a field of view having a first portion depicting the first design configuration and a second portion depicting a second design configuration, as indicated by block 48. In some embodiments, the second user interface is operative to adjust allocation in pixel space of the field-of-view between the first portion and the second portion responsive the user input. For example, in some cases the second user interface may include a user interface element, like a clickable, touchable, or otherwise draggable region that bisects the image and can be slid left and right or up and down (or along some other path), causing two different designs to be depicted in the same view on either side of the line, as the line is moved to show more or less of one designer the other.

Other examples include user interfaces that cause one designed to fade into the other, for example by stacking the two designs and adjusting transparency of one designer the other. In some cases, the user interface may include a circular or rectangular “lens” or other region that can be moved around the field-of-view to show a different design from that depicted in the view surrounding the lens. In some embodiments, individual design elements are selectable, like touchable, clickable, or the like, to transition between different options in the different designs. In some embodiments, two designs may be compared with the second user interface, three designs may be compared to the second user interface (for example with multiple lens user interfaces), or more designs may be compared.

In some embodiments, in the second user interface, the flattened versions of the images depicting the designs are used to expedite the transition between designs, to keep the user interface responsive, or some embodiments may maintain the stacked composited images from the first user interface in the second user interface, and implement the same visual adjustment by manipulating which spatial portions of the stacks are depicted responsive to user interface inputs. Or some embodiments may toggle which layers are depicted using similar techniques.

In some embodiments, the second user interface may include scripting language (or WebAssembly) instructions that map an event handler to an element in a document object model of the user interface that corresponds to user input to make the adjustment of block 48. Examples include a div box, button, or the like. In some embodiments, the user interface element is updated in its position in the window responsive to user input, such that the user interface element appears to be animated sliding along with the user's touch. In some embodiments, the element may snap to positions corresponding to predefined granular adjustments in the view. In some embodiments, the event handler may cause a subroutine to be executed that updates which portions of the images depicting the first and second view design configurations are visible. For example, some embodiments may stack images of the different designs in a div box in the document object model with position attributes set to absolute, and as a slider is adjusted, touch release, on touch, or touch drag events (or corresponding mouse or gaze events) may trigger an event handler mapped to the corresponding user interface element, and that event handler may cause scripts to be executed to dynamically update which portions of the images of the different designs are visible by modulating the clip-path property in cascading style sheets specifications mapped to the images in the div box. Or some embodiments may adjust cropping of images in a canvas element. In some embodiments, these updates to the document object model may be mediated through a shadow document object model using a framework or library like React, Vue, or Angular to make transition smoother and consolidate collections of transitions similar to one another in time to reduce the processing workload for the browser's rendering engine.

In some embodiments, these techniques may be implemented to present user interfaces like those described in FIGS. 3A-3J that illustrate an embodiment in an example use case. In some embodiments, upon selecting a design, user's may be routed to a server of a product manufacturer, e.g., with a uniform resource locator (URL) having a query string that specifies the design, and the user may purchase the product and have it built according to specification.

FIGS. 3A-3D and FIGS. 4A-4F illustrate an example use case of the techniques, described above, to present user interfaces 300 a-300 d and 400 a-40 f, respectively on a display screen 302/402 included on a client 14 of FIG. 1 . FIG. 3A illustrates the user interface 300 a. The user interface 300 a may include a base image 304. As described above, the base image may depict a field-of-view of the article of manufacture, or portion thereof, like a view into a kitchen of a house or commercial property to be designed, or into an automobile interior, or of a model wearing an article of clothing. The base image may include a base division (div) hypertext markup language (HTML) element with a background image to present an initial scene.

FIG. 3B illustrates the user interface 300 b. Inside the base div HTML, additional div elements may be added with full width and height to show layers. As such, user interface 300 b may include a template image 306. As discussed above, template images may be overlaid on the base image to depict different design options. For example, the base image may depict a countertop with a blue surface, and the template image 306 may include a view of that countertop with a green surface, both having the pixels depicting the countertop in the same positions in pixel space (e.g., at the same Cartesian coordinates in the image). In some embodiments, the template image 306 may include a first portion 306 a with pixel values that are nontransparent and overlay and occlude pixels in the base image to depict the design option. The template image 306 may further include a second portion 306 b with pixels that are transparent, such that when overlaid on the base image, the pixels of the base image are still viewable.

FIG. 3C illustrates the user interface 300 c. The user interface 300 c may include a template image 308. The template image 308 may include a first portion 308 a with pixel values that are nontransparent. As illustrated, the first portion 308 a includes an image of a facet. The template image 308 may include a second portion 308 b with pixels that are transparent.

FIG. 3D illustrates the user interface 300 d. The user interface 300 d may include a composite image 310 that includes a stack of the template images 306 and the base image 304. As can be seen from FIG. 3D, the first portion 306 a (e.g., a countertop), illustrated in FIG. 3B, and the second portion 308 b (e.g., a facet), illustrated in FIG. 3C, are now stacked on the base image 304 to form the composite image 310.

FIGS. 4A-4F illustrate presented user interfaces 400 a-400 g on a display screen 402 include on a client 14 of FIG. 1 . In FIG. 4A, the user interface 400 a depicts a field of view 403 having a first portion 404 depicting a first design configuration 404 a and a second portion 406 depicting a second design configuration 406 a, as discussed above with respect to block 48. In some embodiments, the user interface 400 a is operative to adjust allocation in pixel space of the field-of-view between the first portion 404 and the second portion 406 responsive the user input. For example, in some cases the user interface 400 a may include a user interface element 408, like a clickable, touchable, or otherwise draggable region that bisects the image and can be slid left and right or up and down (or along some other path), causing two different designs to be depicted in the same view on either side of the line, as the line is moved to show more or less of one designer the other. For example, FIG. 4B illustrates the user interface element 408 moved to the top of the display such that primarily the second portion 406 is viewed on the user interface 400 b such that the second design configuration 406 a may be presented. FIG. 4C illustrates the user interface 400 c where the first design configuration 404 a and the second design configuration 406 a are swapped such that the first portion 404 of the field of view 403 may present the second design configuration 406 a and the second portion 406 of the field of view may present the first design configuration 404 a.

In FIG. 4D, the user may have selected that the user interface element 408 is positioned in a vertical orientation rather than a horizontal orientation as illustrated in FIGS. 4A-4C. As such, the user interface 400 d depicts a field of view 403 having a first portion 404 depicting a first design configuration 404 a and a second portion 406 depicting a second design configuration 406 a. FIG. 4E illustrates the user interface element 408 moved to the left of the user interface 400 e such that primarily the first portion 404 is viewed on the user interface 400 e or that the first design configuration 404 a may be presented. FIG. 4F illustrates the user interface 400 f where the first design configuration 404 a and the second design configuration 406 a are swapped such that the first portion 404 of the field of view 403 may presented by the second design configuration 406 a and the second portion 406 of the field of view may present the first design configuration 404 a.

FIG. 5 illustrates an embodiment of a session collaboration system 500. In the illustrated embodiment, the session collaboration system 500 may include one or more client computing devices 502. The one or more client computing devices 502 may include the clients 14 of FIG. 1 . The session collaboration system 500 may include a host computing device 504. The host computing device 504, in some instances, may include a client computing device 502. Likewise, in some embodiments, any of the client computing devices 502 may include the host computing device 504. The host computing device 504 may initiate a collaboration session that the client computing devices 502 may participate, as discussed in further detail below.

In various embodiments, the session collaboration system 500 may include a server computing device 506. The server computing device 506 may include and perform the functionality of the server 12 of FIG. 1 . For example, the server computing device 506 may include one or more servers, storage systems, cloud computing systems, and/or other computing devices (e.g., desktop computing device(s), laptop/notebook computing device(s), tablet computing device(s), mobile phone(s), etc.). As discussed below, the server computing device 506 may be coupled to a database 512 that is configured to provide repositories such as user accounts, design configurations, sets of images compositable to depict different design configurations, design session information, user information of participants in a design session, builder information, home plan or other design plan information, client computing device identifier information, host computing device identifier information, or any other information discussed below or that would be apparent to one of skill in the art in possession of the present disclosure.

Also, the server computing device 506 may be configured to computationally process sensor data received from the client computing devices 502 or the host computing device 504 and render instructions to the client computing devices 502 or the host computing device 504. For example, the server computing device 506 may provide a session collaboration visualizer engine 508 to the client computing devices 502 and the host computing device 504. The server computing device 506 may establish the secure session connections, provide sets of images compositable to depict different design configurations, or any of the other functionality of the configuration engine 16 or rendering engine 18, discussed above, or perform other functionality discussed below. As such, the server computing device 506 may include communication units having one or more transceivers to enable the server computing device 506 to communicate with the client computing devices 502 or the host computing device 504 via a network (e.g., the network 20 of FIG. 1 ). Accordingly, as discussed in further detail below, the server computing device 506 may be in communication with the client computing devices 502 or the host computing device 504 directly or indirectly. As used herein, the phrase “in communication,” including variances thereof, encompasses direct communication and/or indirect communication through one or more intermediary components and does not require direct physical (e.g., wired and/or wireless) communication and/or constant communication, but rather additionally includes selective communication at periodic or aperiodic intervals, as well as one-time events.

For example, the client computing devices 502, the host computing device 504, and the server computing device 506 in the session collaboration system 500 of FIG. 5 may include first (e.g., relatively long-range) transceiver(s) to permit the client computing devices 502, the host computing device 504, and the server computing device 506 to communicate with the network 50 via a communication connection. In various embodiment and during a design session. The client computing devices 502 and the host computing device 504 may negotiate with the server computing device 506 to establish connections for the design session. The server computing device 506 may redirect the connection requests to a content push service 510, which may include a cloud-based content push service. For example, the content push service 510 may include Azure SignalR Service provided by MICROSOFT® CORP. of Redmond, WA, USA. However, other content push services may be used. This real-time functionality of the content push service 510 may allow the session collaboration service to push content updates to connected client computing device 502 or the host computing device 504, such as a single page web or mobile application. As a result, the client computing device 502 or the host computing device 504 are updated without the need to poll the server computing device 506, or submit new HTTP requests for updates. In various embodiments, the content push service 510 may be hosted by the server computing device 506 instead of a separate computing device. The content push service 510 may establish secure connections between each of the client computing devices 502 and the content push service 510. The content push service 510 may also establish a secure connection between the host computing device 504 and the content push service 510. The content push service 510 may also establish one or more secure connections between the content push service 510 and the server computing device 506.

In various embodiments, the secure connection may be generated according to a full-duplex communication protocol such as, for example, Web Socket, and/or any other full-duplex communication protocol that would be apparent to one of skill in the art in possession of the present disclosure. In an embodiment, other protocols that may be used to generate a secure connection or tunnel include hypertext transfer protocol (HTTP) over transport layer security (TLS)/secure socket layer (SSL), secure shell protocol (SSH), WebSocket over transmission control protocol (TCP), server-sent events (SSE), long polling, or any other secure connection protocol.

The session collaboration system 500 may operate on a network, such as the network 50 of FIG. 1 . The network may be implemented by an example mobile cellular network, such as a long-term evolution (LTE) network or other third generation (3G), fourth generation (4G) wireless network, or fifth-generation (5G) wireless network. However, in some examples, the network may be additionally or alternatively be implemented by one or more other communication networks, such as, but not limited to, a satellite communication network, a microwave radio network, wired communication systems, Wi-Fi communication systems, and/or other communication networks.

The client computing devices 502 or the host computing device 504 additionally may include second (e.g., relatively short-range) transceiver(s) to permit the client computing devices 502 or the host computing device 504 to communicate with each other via a direct communication connection. Furthermore, the second transceiver may be used for client device-to-client device communications between the client computing devices 502 or the host computing device 504 and other client computing devices or host computing devices. In the illustrated example of FIG. 5 , such second transceivers are implemented by a type of transceiver supporting short-range (e.g., operate at distances that are shorter than the long-range transceivers) wireless networking. For example, such second transceivers may be implemented by a Wi-Fi transceiver (e.g., via a Wi-Fi Direct protocol), a Bluetooth® transceiver, an infrared (IR) transceiver, a Zigbee transceiver, and/or other transceivers that are configured to allow the client computing device 502 or the host computing device 504 to intercommunicate via a direct communication connection or a Local Area Network (LAN). While a session collaboration system 500 has been illustrated and described, one of skill in the art in possession of the present disclosure will recognize that the teachings of the present disclosure will be beneficial for a variety of session collaboration systems that would be apparent to one of skill in the art in possession of the present disclosure and, as such, a wide variety of modifications to the number, types, and orientation of devices in the session collaboration system 500 will fall within the scope of the present disclosure as well.

FIG. 6 illustrates a session collaboration visualizer engine architecture 600. The session collaboration visualizer engine architecture 600 includes a session collaboration visualizer engine 602 that may be the session collaboration visualizer engine 508 of FIG. 5 . The session collaboration visualizer engine 602 may include a rendering engine 602 a and a configuration engine 602 b that may be also referred to as a “wrapper” herein. The rendering engine 602 a may include the rendering engine 18 of FIG. 1 and the configuration engine 602 b may include the configuration engine 16 of FIG. 1 .

The session collaboration visualizer engine 602 may interface and exchange communications with the host computing device 604 that may include the host computing device 504 of FIG. 5 . The session collaboration visualizer engine 602 may also interface and exchange communications with a unified user profile (UUP) service 606 that may be used to authenticate and verify a user of the host computing device 604. While not illustrated, the host computing device 604 may include the client computing devices 502 of FIG. 5 . The host computing device 604 may includes one or more native applications or browser-based applications (e.g., Webarch or New Home Source (NETS)) that may interface with the session collaboration visualizer engine 602.

In various embodiments, the session collaboration visualizer engine architecture 600 may include an application programming interface (API) layer 608. The application programming interface layer 608 may interface and exchange communications with the session collaboration visualizer engine 602. An NHS API 610, which may provide an API for third-party systems (e.g., a partner API, a builder API, a brand API, a community API, a building plan API, or other third-party API), may interface and exchange communications via the API layer 608. Building plans, builder information, community plans, sets of images, design configurations, or other content and information may be provided via the NHS API 610. The NHS API 610 may be an API for a web-based service such as new home source (NHS) for designing homes but may be for other design-based services for other products besides homes. This content or information may be stored at a database 612, which may include the database 512 of FIG. 5 . The API layer 608 may interface and communicate with the database 612 to provide assets 614 (e.g., content) such as images, fonts, design configurations, or other content discussed herein to the session collaboration visualizer engine 602 via a content delivery network 616.

In various embodiments, the API layer 608 may interface and exchange communications with an administrator console 618 such that administrators 620 may interact with and conduct administrative activities on the session collaboration visualizer engine architecture 600. While a specific session collaboration visualizer engine architecture 600 is illustrated, a person of skill in the art in possession of the present disclosure will recognize that the teachings of the present disclosure will be beneficial for a variety of session collaboration visualizer engine architectures that would be apparent to one of skill in the art in possession of the present disclosure and, as such, a wide variety of modifications to the number, types, and orientation of devices and modules in the session collaboration visualizer engine architecture 600 will fall within the scope of the present disclosure as well.

FIG. 7 illustrates a flowchart of session collaboration during a method 700 of designing a virtual space, according to various embodiments of the present disclosure. In some embodiments, the server computing device 506 may execute the method 700 illustrated in FIG. 7 or some of the method 700 may be executed by the host computing device 504 or the client computing device 502, for example, by executing program code stored on a tangible, non-transitory, machine-readable medium. The illustrated operations may be executed in a different order, omitted, replicated, executed concurrently, executed serially, have additional operations inserted, all be automated, involve human intervention, or otherwise be modified relative to the arrangement depicted, which is not to suggest that any other description herein is limiting.

The method 700 may begin at block 702 where a design session is established with a plurality of client computing devices. In an embodiment, at block 702, the host computing device 504 may initiate a design session for collaboration with one or more client computing devices 502. The host computing device 504 may send a request to the server computing device 506 to initiate the design session. A design session may be initiated by the server computing device 506. The design session may include a token associated with the design session or other session identifier.

Once the session is initiated, the server computing device 506 may act as a broker and redirect the host computing device 504 to the content push service 510. For example, the host computing device 504 may send a negotiate request to the server computing device 506. The server computing device 506 may return a redirect response with a URL for the content push service 510 and access token. The host computing device 506 uses the URL and the access token to establish a host connection (e.g., a persistent connection) with the content push service 510. The content push service 510 may locate a server connection that has been previously established between the server computing device 506 and the content push service 510. The content push service 510 will map the server connection with the host connection and the mapping will be maintained until the host computing device 504 or the server computing device 506 disconnects. In some embodiments, the host connection and the server connection may be established according to WebSocket protocol. However, other protocols may be used to establish the persistent connections, as discussed above. At this point, the server computing device 506 may receive an event with information from the host computing device 504. A logical connection to the host computing device 504 is created in the server computing device 506, thus creating a data channel. The data channel is established from the host computing device 504 to the server computing device 506, via content push service 510. The server computing device 506 may push content, other information or instructions for the design session via the data channel to the host computing device 504.

The other client computing device 502 may also join the design session and establish a data channel with the server computing device 506 according to the same process as the host computing device 504. Once the session is established and the client computing devices 502 and the host computing device 504 are associated with the design session via the session identifier, the content push service 510 may transmit data received from the client computing device 502 or the host computing device 504 to the server computing device 506. Also, the content push service 510 will transmit data from the server computing device 506 to the mapped client computing devices 502 and the host computing device 504, as discussed in further detail below.

In some embodiments, the method 700 is preceded by one or more product manufacturers, which may be different tenants having different tenant accounts supported by the server computing device 506, supplying a set of records characterizing a respective design space, among a plurality of design spaces. In some embodiments, the set of records may include computer aided design files specifying a spatial arrangement of a product to be manufactured, like a home, landscaping design, automobile, computer, furniture, or article of clothing. The set of records may further include various options for components, which may include different, substitutable computer-aided design (CAD) files for different shapes of components, like different fixtures, as well as different textures corresponding to different surfaces, like image files to be tiled over polygons that define a surface specified by the CAD files. In some embodiments, the records may further indicate which optional resources correspond to which surfaces or spatial areas of the CAD file. Options may further include lighting options, which may include attributes of the light to be used in renders.

In some embodiments, this set of records may be received by the above-described configuration engine 602 b, which may cooperate with the rendering engine 602 a to provide data that allows the server computing device 506 to obtain a set of images compositable to depict different designs in a design space, as indicated by block 704 in FIG. 7 . For example, the set of records may be received via the API layer 608 from the NHS API 610 and provide those records in the database 612 or as assets 614. In some embodiments, the set of images may include substantially fewer images than there are possible designs supported in the design space. For example, the number of images may scale at a rate of less than some coefficient of the number of designs supported by a specified design space corresponding to the set of images, or the design space may have a number of designs that scales at an exponential rate relative to the number of images needed to depict all of the designs in that space or a lower rate. As a result, some embodiments may substantially reduce the computational complexity of the described operations in terms of memory complexity relative to more naïve approaches that obtain a different image for every single possible design in a design space. That said, embodiments are also consistent with this more naïve approach in some cases, for example, where the design spaces are relatively low dimensional and coarse-grained.

In some embodiments, the set of images may include images like those described herein in a technical description of an example embodiment having in-line images. In some embodiments, the set of images may include a base image depicting a field-of-view of the article of manufacture, or portion thereof, like a view into a kitchen of a house or commercial property to be designed, or into an automobile interior, or of a model wearing article of clothing. In some embodiments, the base image may have no transparency in the entire image or a portion depicting the field-of-view. In some embodiments, the base image is a three-dimensional perspective view of the field-of-view. In some cases, the rendering engine 602 a may execute a ray-tracing algorithm to render the images, in some cases, masking or isolating given objects to create the templates described below.

In some embodiments, the set of images includes template images to be overlaid on the base image to depict different design options. For example, the base image may depict a countertop with a blue surface, and a template image may include a view of that countertop with a green surface, both having the pixels depicting the countertop in the same positions in pixel space (e.g., at the same Cartesian coordinates in the image). In some embodiments, the template images may include a first portion with pixel values that are nontransparent and overlay and occlude pixels in the base image to depict the design option. The template images may further include a second portion with pixels that are transparent, such that when overlaid on the base image, the pixels of the base image are still viewable. The transparent pixels need not be perfectly transparent to qualify as such, provided the visual effect of the base image or other layered images remains for the viewer. For example, the transparent pixels may be less than more than 80% transparent, 90% transparent, 95% transparent, 99% transparent, or 99.9% transparent while still qualifying as “transparent.”

In some embodiments, the images in the set may be in a format that supports transparency, for example portable network graphics (PNG) format, joint photographic experts group extended range (JPEG XR) format, WebP format, or the like. In some embodiments, the image file format may include an alpha channel, separate from, for example, red, blue, and green channels that specify intensities for each of several colors constituting the pixel. In some embodiments, the alpha channel may specify transparency of the corresponding pixel at the coordinates of that pixel, like Cartesian coordinates of height and width. In some embodiments, the alpha channel may have a bit depth of 4, 8, 16, or 32 bits, or more or less corresponding to different degrees of transparency. In some embodiments, the image format may be a lossy compression format or a lossless compression format, depending upon design trade-offs in image quality, latency, and bandwidth consumption. Some embodiments may compress the image by segmenting it into square blocks, computing a discrete wavelet transform (e.g., with a fast Fourier transform) of various spatial variation of pixel intensity in the channel within each block, quantizing the resulting matrix by multiplying it with a quantization matrix tuned to down-res higher frequency components, and then compressing the result with run-length coding or dictionary coding. The client computing device may reverse this process with a suitable image decoder to determine pixel intensities and display the image, thereby conserving memory, bandwidth, and latency.

In some embodiments, each of the images in the set may have the same height and width in pixel space, such that when the images are overlaid, the position of the second portion in the template images is at a specified portion of the first portion, for instance causing an overlay of a countertop surface design choice to be in the proper position. Or in some cases, template images may be smaller and may include a height and width offset that specifies an alignment point for overlay.

In some embodiments, the template images are associated with a depth value, like an integer depth value, such as a z value, and template images may be applied to a base image in a stack according to these depth values, monotonically increasing or decreasing, depending upon the numbering scheme. This is expected to accommodate scenes in which portions affected by different design options overlie one another in the field of view.

In some embodiments, the images in the set may be created by the rendering engine 602 a in cooperation with the configuration engine 602 b. In some embodiments, the configuration engine 602 b may execute a script that causes the configuration engine 602 b to generate polygon volumetric meshes and surface tiling of every permutation of supported design and provide those outputs to the rendering engine 602 a to cause the rendering engine 602 a to render corresponding images. In some embodiments, the rendering engine 602 a (e.g., Unreal Engine from Epic Games Inc. of Cary, North Carolina) may be directed to generate a single base image for each three-dimensional polygon mesh and then generate template images for all options of textures that are supported in the design space. In some embodiments, this process may be repeated for multiple sets corresponding to different views of different portions of the product, and the operations described may be replicated for those different views. For example, a user may configure their kitchen in one set of user interfaces and their bathroom in another. In some embodiments, the images may be generated in advance of a session with the user with preprocessing, as image generation may be relatively computationally complex and time-consuming, possibly taking more than 10 minutes or 10 hours to cover all permutations of a design space. Or some embodiments may implement real-time server-side or client-side rendering, e.g., when the design space is particularly high dimensional and complex. The resulting images may be indexed according to the design options to which they correspond, and the configuration engine 602 b may provide an ontology of those options along with the corresponding images to the server computing device 506, which may store them in a repository for use when generating user interfaces in subsequent steps.

In some embodiments, the rendering engine 602 a may be operative to perform certain operations to reduce edge artifacts in template images to improve the visual quality of composite images in which those templates are stacked on a base image, in some cases with multiple (3, 5, 10, or more) such template images stacked. In some embodiments, the rendering engine 18 may implement alpha compositing with those template images. In some embodiments, the rendering engine or associated raster graphics editor, may apply a Gaussian blur on the alpha channel of the template images (e.g., only the alpha channel and not in the other channels), for example a five pixel by five pixel Gaussian kernel, a three pixel by three pixel Gaussian kernel, or different size Gaussian kernel for a convolution may be applied to the alpha channel but not other channels, in some cases. In some embodiments, the transformation may be performed after converting the initial images from a non-linear color space, like sRGB, to a linear color space, and then after the transformation to smooth edges in the alpha channel, the images may be converted back to a non-linear color space. In some embodiments, the alpha channel may be a straight unassociated alpha channel or a pre-multiplied associate alpha channel. In some embodiments, these operations may result in a gradient of transparency at edges of the first portions of the template images, which are expected to reduce artifacts at edges, like ugly jagged lines and discordant color transitions in composite images displayed in client-side user interfaces. In some embodiments, the rendering engine 602 a may include or may communicate with a raster graphics editor program, such as one scripted to implement these transformations or instructed implement these transformations through system calls, like Gimp or ImageMagick. Or some embodiments may implement compositing without adjusting the alpha channel, which is not to suggest that any other description is limiting.

In some embodiments, the method 700 further includes providing a first user interface by which members of the set are overlaid responsive to user inputs to depict different design configurations, as indicated by block 706. In some embodiments, this operation may be performed by the server computing device 506 by sending markup styling and scripting what language instructions to the client computing devices 502 and the host computing device 504 responsive to a request for such a user interface (e.g., one including a user identifier by which the session may be associated with a profile), along with corresponding visual assets and data used to effectuate different views to be presented responsive to user inputs. In some embodiments, this transmission may be responsive to a request for a specific view or product from the one of the client computing devices 502, for example, via a web browser or native application. In some embodiments, the user interface may be provided by sending assets 614 and data to a native application otherwise having code and other instructions needed to populate the user interface.

In some embodiments, providing the user interface may include sending images that are not immediately displayed to hold in a client-side cache to afford a relatively responsive updates to the user interface after user inputs. For example, some embodiments may send a subset of template images selected based upon a user's profile that are predicted to be likely to be chosen or were previously designated as “favorites.” In some embodiments, the user interface may take the form of that shown below in the appended technical documentation. In some embodiments, this first user interface may include inputs by which a user selects which design element is to be configured and inputs by which the user selects among options for that design element, for instance, by clicking, touching, or voicing spoken instructions to make selections. In some embodiments, user interfaces may be presented in virtual reality or augmented reality with a head-mounted display, and inputs may be implemented with gaze tracking or pointing. User inputs may be mapped to event handlers that update the user interface by manipulating a document object model to reflect the user's selection and update program state, e.g., swapping in and out template images in a stack of such images overlaying a base image to reflect user design choices.

In some embodiments, the first user interface may include the same design configuration of the space but may provide different viewpoints of the space according to each user. As such, some data is pushed from the server computing device 506 to the client computing devices 502 and the host computing device 504 via the content push service 510 (e.g., images for the design space and design configurations) while other data is not pushed via the content push service 510 (e.g., pose, such as location and viewpoint, of a user in the design space). As such, the design space may be the same for all of the participants in the design session even if a particular user is not viewing a particular room or angle within the design space.

In some embodiments, the first user interface executing on the client computing device 502 may present these options and receive inputs from the user to select among them. Responsive to receiving a user selection of a given design option, the first user interface may access from cache or request from the server computing device 506 a corresponding template image depicting the user selection (e.g., a given design option). The server computing device 506 may provide the image or instructions to use the image via the content push service 510 to the remaining client computing devices 502 or the host computing device 504. The user interface may, upon receiving that image or accessing that image, determine a position in a stack of images currently composited in the user interface to receive the newly selected template image, based upon a depth value of the image and depth values of the other images in the stack, maintaining the stacked images in depth order in a composite view. In some embodiments, the images may be stacked in a div box in a document object model with which the user interface is implemented in a web browser. In some embodiments, the images that are stacked may have their position attributes set to absolute to control alignment as, for example, the screen is resized.

In some embodiments, the user interface may maintain a design state record for the session, which in some cases may be saved to a user profile server-side or client-side, so that the current state of the user interface may be re-created by, for example, replaying a set of user selections in a log, or stacking the specified template images for a design recorded in the profile. In some embodiments, the user interfaces may include an input by which a user may save their design or name their design.

In some embodiments, upon naming or otherwise designating a design, the stacked set of images may be flattened into a flat, single image of the design, which may be stored in memory in association with the user's profile (e.g., in client-side cache or server-side). In some embodiments, a design image may be named according to the response of a hash function to a text specification of the existing design, such that identical designs are assigned the same hash value as a name, and duplicate instances of the same design selected by different consumers may be maintained in memory with a single image file server side to save memory. In some embodiments, the flattening of the image may be performed server-side with the above-described image raster graphics editors, or some embodiments may flatten the image client-side, for example, by invoking WebGL functionality to expedite image processing operations via the browser by concurrently combining pixel values in a stack in different regions with different pixel shaders of a graphics processing unit (GPU) of the client computing devices 502 or the host computing device 504.

In some embodiments, as a result of the user designating a design, some embodiments of the server computing device 506 may obtain a first design configuration specified via the first user interface, as indicated by block 708. The specification may include identifiers of the images stacked in the design, a log of user edits to the design from the base design, or an inventory of design elements chosen in the design, for example. In some embodiments, this design configuration may be stored along with a plurality of other design configurations chosen by the user. In some embodiments, the server computing device 506 may further store in memory a set of public design configurations (also referred to as designs), for example, chosen by interior design specialists or architects or other experts in the design domain, and users may also access these to compare against their own configurations or to compare configurations of designs from different preset alternatives. The server computing device 506 may push the design configuration to the other client computing device 502 and the host computing device 504, in block 710, such that the design space can be viewed concurrently by users of the client computing device 502 and the host computing device 504 in real-time.

In various embodiments, the design session may provide chat, video, or audio feeds in the user interface that is displayed at the client computing devices 502 and the host computing device 504 during the collaboration session. These features may be provided through the content push service 510 as well. As such, participants may communicate with each other in real-time to discuss the design space while also viewing changes made by each user to the design space in real-time. However, some activities of the session may be independent of the other users in the session. For example, the field of view and location of each user in the design space may be different. One client computing device 502 may be providing a user interface of a bedroom while another client computing device 502 may be providing a user interface of a kitchen of the same design space. Thus, when the user that was the viewing bedroom moves to the kitchen, that user may view the design configuration that was last imputed by the other client computing device 502 when in the kitchen. However, in other embodiments, the design space may be viewed from the same point of view as all other users or a portion of the users in the collaboration session.

In various embodiments, the design configuration created by the user of the host computing device 504 or a client computing device 502 may not be pushed by the server computing device 506 to other client computing devices 502 until various conditions occur. For example, the design configuration created by the host computing device 504 may not be pushed by the server computing device 506 to a client computing device 502 until a current user interface for the client computing device of the design space satisfies a position condition. Specifically, if the client computing device 502 is viewing the design space at a location that is not near or in view of the portion of the design space that the host computing device 504 is viewing and has changed the design configuration, the server computing device 506 may not push or otherwise provide that portion of the design space to the client computing device 502 until that user interface for the client computing device 502 is within a predetermined distance, pose, or other area defined in the design space. In a specific example, if the host computing device 504 changes the countertops in the kitchen and the field of view of the client computing device 502 is depicting the design space in a bedroom, the server computing device 506 may not push the design configuration for the kitchen until the field of view of the client computing device 502 is in a room next to the kitchen, in the kitchen itself, or until the client computing device 502 has a field of view where the countertops are visible. This reduces the number of pushes over the network and computational processing of the client computing device 502 if the client computing device 502 never has the field of view of the countertops during the design session. Furthermore, the countertops or other features of the kitchen may undergo other changes while the user of the host computing device 504 is in the field of view of the kitchen which could create several new design changes to the design configuration. As such, if each of these changes are pushed to the client computing devices 502 whenever they are made, even though the client computing devices 502 are not viewing that area, this can greatly increase latency on the entire design session due to a plurality of pushes and updates to the client computing device 502. Thus, by delaying pushes of the design configurations until the client computing device 502 is in the field of view or is in a predetermined proximity of the field of view will reduce the number of pushes on the network.

In another example, a granularity of processing the new design configuration may be implemented. For example, the server computing device 506 may push the design configuration created by the host computing device 504 to the client computing device 502 when the client computing device 502 has a field of view that satisfies a first position condition. The client computing device 502 may cache that design configuration until the field of view of the client computing device 502 satisfies a second position condition where the client computing device 502 may then render that design configuration and display it. As such, processing of the design configurations at the client computing device 502 can be reduced such that the design configurations are not processed by the client computing devices 502 until the field of view of the client computing device 502 requires it.

In another embodiment, design configurations may only be captured and sent to other participating client computing devices 502 when a depiction condition is satisfied. In an embodiment, the depiction condition may occur when the design configuration has been displayed for a predetermined period of time at the originating host computing device 504 or the originating client computing device. As such, quick edits or cycles between design selection made by a user of, for example, the host computing device 504 may not be captured and pushed in a design configuration to client computing devices 502 until a final selection has been depicted in the field of view of the host computing device 504 for a predetermined duration of time. Referring to the example regarding the countertops, if the user of the host computing device 504 selects several different countertops when determining which one she likes best, each of the intermediate selections will not be captured by the server computing device 506 and pushed to the client computing devices 502 in the new design configuration until the most current countertop design has been idle for a predetermined duration of time. (e.g., 5 seconds, 15 seconds, 30 seconds, 1 minute). As such, every intermediate change of the countertops will not be captured and processed as a design configuration that would be pushed to the client computing devices 502. This reduces processing and reduces traffic on the data channels. In some embodiments, the duration of time to satisfy the depiction condition may be based on where the field of view of the client computing device is positioned in the design space. For example, the intermediate design changes of the countertops may be captured and pushed to a client computing device 502 if the field of view of that client computing device 502 is viewing the countertops with the user of the host computing device 504 while the push may not occur to another client computing device that is not in the field of view of the countertops until a longer duration of idleness of changes to the countertops occurs. While it is discussed that the server computing device 506 may be receiving the design configuration updates from the host computing device and then delaying a push of that design configuration to client computing device 502 until a condition is satisfied, in various embodiments, the host computing device 504 may be making changes to locally cached images in the design space and those updated design configurations are only made available to the server computing device 506 when the condition is satisfied (e.g., a depiction condition, a position condition, etc.).

As such, network communications between the host computing device 504 and the server computing device may also be reduced.

Thus, the systems and methods of the present disclosure provide a collaborative design session where users accessing a design space from different client computing devices can make edits to the design space and those edits are visible to other users participating in the collaborative design session even when those users are not at the same field of view as the user that made the edits. As such, users can collaborate in the design of a design space or object by making real-time changes. Furthermore, the systems and methods of the present disclosure reduce latency, reduce storage requirements, and other computational resources by locally caching images that are to be overlaid based on the location of a user in the design space as well as other technological improvements discussed herein.

The reader should appreciate that the present application describes several independently useful techniques. Rather than separating those techniques into multiple isolated patent applications, applicants have grouped these techniques into a single document because their related subject matter lends itself to economies in the application process. But the distinct advantages and aspects of such techniques should not be conflated. In some cases, embodiments address all of the deficiencies noted herein, but it should be understood that the techniques are independently useful, and some embodiments address only a subset of such problems or offer other, unmentioned benefits that will be apparent to those of skill in the art reviewing the present disclosure. Due to costs constraints, some techniques disclosed herein may not be presently claimed and may be claimed in later filings, such as continuation applications or by amending the present claims. Similarly, due to space constraints, neither the Abstract nor the Summary of the Invention sections of the present document should be taken as containing a comprehensive listing of all such techniques or all aspects of such techniques.

It should be understood that the description and the drawings are not intended to limit the present techniques to the particular form disclosed, but to the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present techniques as defined by the appended claims. Further modifications and alternative embodiments of various aspects of the techniques will be apparent to those skilled in the art in view of this description. Accordingly, this description and the drawings are to be construed as illustrative only and are for the purpose of teaching those skilled in the art the general manner of carrying out the present techniques. It is to be understood that the forms of the present techniques shown and described herein are to be taken as examples of embodiments. Elements and materials may be substituted for those illustrated and described herein, parts and processes may be reversed or omitted, and certain features of the present techniques may be utilized independently, all as would be apparent to one skilled in the art after having the benefit of this description of the present techniques. Changes may be made in the elements described herein without departing from the spirit and scope of the present techniques as described in the following claims. Headings used herein are for organizational purposes only and are not meant to be used to limit the scope of the description.

As used throughout this application, the word “may” is used in a permissive sense (i.e., meaning having the potential to), rather than the mandatory sense (i.e., meaning must). The words “include”, “including”, and “includes” and the like mean including, but not limited to. As used throughout this application, the singular forms “a,” “an,” and “the” include plural referents unless the content explicitly indicates otherwise. Thus, for example, reference to “an element” or “a element” includes a combination of two or more elements, notwithstanding use of other terms and phrases for one or more elements, such as “one or more.” The term “or” is, unless indicated otherwise, non-exclusive, i.e., encompassing both “and” and “or.” Terms describing conditional relationships, e.g., “in response to X, Y,” “upon X, Y,”, “if X, Y,” “when X, Y,” and the like, encompass causal relationships in which the antecedent is a necessary causal condition, the antecedent is a sufficient causal condition, or the antecedent is a contributory causal condition of the consequent, e.g., “state X occurs upon condition Y obtaining” is generic to “X occurs solely upon Y” and “X occurs upon Y and Z.” Such conditional relationships are not limited to consequences that instantly follow the antecedent obtaining, as some consequences may be delayed, and in conditional statements, antecedents are connected to their consequents, e.g., the antecedent is relevant to the likelihood of the consequent occurring. Statements in which a plurality of attributes or functions are mapped to a plurality of objects (e.g., one or more processors performing steps A, B, C, and D) encompasses both all such attributes or functions being mapped to all such objects and subsets of the attributes or functions being mapped to subsets of the attributes or functions (e.g., both all processors each performing steps A-D, and a case in which processor 1 performs step A, processor 2 performs step B and part of step C, and processor 3 performs part of step C and step D), unless otherwise indicated. Similarly, reference to “a computer system” performing step A and “the computer system” performing step B can include the same computing device within the computer system performing both steps or different computing devices within the computer system performing steps A and B. Further, unless otherwise indicated, statements that one value or action is “based on” another condition or value encompass both instances in which the condition or value is the sole factor and instances in which the condition or value is one factor among a plurality of factors. Unless otherwise indicated, statements that “each” instance of some collection have some property should not be read to exclude cases where some otherwise identical or similar members of a larger collection do not have the property, i.e., each does not necessarily mean each and every. Limitations as to sequence of recited steps should not be read into the claims unless explicitly specified, e.g., with explicit language like “after performing X, performing Y,” in contrast to statements that might be improperly argued to imply sequence limitations, like “performing X on items, performing Y on the X'ed items,” used for purposes of making claims more readable rather than specifying sequence. Statements referring to “at least Z of A, B, and C,” and the like (e.g., “at least Z of A, B, or C”), refer to at least Z of the listed categories (A, B, and C) and do not require at least Z units in each category. Unless specifically stated otherwise, as apparent from the discussion, it is appreciated that throughout this specification discussions utilizing terms such as “processing,” “computing,” “calculating,” “determining” or the like refer to actions or processes of a specific apparatus, such as a special purpose computer or a similar special purpose electronic processing/computing device. Features described with reference to geometric constructs, like “parallel,” “perpendicular/orthogonal,” “square”, “cylindrical,” and the like, should be construed as encompassing items that substantially embody the properties of the geometric construct, e.g., reference to “parallel” surfaces encompasses substantially parallel surfaces. The permitted range of deviation from Platonic ideals of these geometric constructs is to be determined with reference to ranges in the specification, and where such ranges are not stated, with reference to industry norms in the field of use, and where such ranges are not defined, with reference to industry norms in the field of manufacturing of the designated feature, and where such ranges are not defined, features substantially embodying a geometric construct should be construed to include those features within 15% of the defining attributes of that geometric construct. The terms “first”, “second”, “third,” “given” and so on, if used in the claims, are used to distinguish or otherwise identify, and not to show a sequential or numerical limitation. As is the case in ordinary usage in the field, data structures and formats described with reference to uses salient to a human need not be presented in a human-intelligible format to constitute the described data structure or format, e.g., text need not be rendered or even encoded in Unicode or ASCII to constitute text; images, maps, and data-visualizations need not be displayed or decoded to constitute images, maps, and data-visualizations, respectively; speech, music, and other audio need not be emitted through a speaker or decoded to constitute speech, music, or other audio, respectively. Computer implemented instructions, commands, and the like are not limited to executable code and can be implemented in the form of data that causes functionality to be invoked, e.g., in the form of arguments of a function or API call. To the extent bespoke noun phrases (and other coined terms) are used in the claims and lack a self-evident construction, the definition of such phrases may be recited in the claim itself, in which case, the use of such bespoke noun phrases should not be taken as invitation to impart additional limitations by looking to the specification or extrinsic evidence.

In this patent, to the extent any U.S. patents, U.S. patent applications, or other materials (e.g., articles) have been incorporated by reference, the text of such materials is only incorporated by reference to the extent that no conflict exists between such material and the statements and drawings set forth herein. In the event of such conflict, the text of the present document governs, and terms in this document should not be given a narrower reading in virtue of the way in which those terms are used in other materials incorporated by reference.
